I was really amazed by this processor. Even though the stock speed is 2.2 GHz, I was able to overclcock it to a speed of 3.0 GHz.It was fully stable and stayed at a maximum of 55 degree celcius which is quite okay. It runs more powerful than pentium dual core and other processors which are in or above its price range. I was able to play NFS MW, NFS CARBON,MANHUNT,FLATOUT,GTA IV and ps3 games using emulators without lagging.There is nothing I don't like about it. I liked to know its price range and power efficiency before purchase. Its an overclocking daemon at even stock cooling. I recommend this product 100% to all. I've been using it for 3 years @ 3.0 GHz. I like it.
